ARM: ux500: Initial support for PM domains
The ux500 SoC uses the generic PM domain and requires the domains to be
specified through DT.
Currently the genpd callbacks for handling power gating|ungating are
implemented as dummy functions. To be able to enable those to perform
PM domain gating/ungating, each device that resides in the VAPE domain
must be properly handled from a runtime PM perspective.
